    Icon32 12" Fi BTL N3 enclosure NEED HELP.

    So what we have:

    Golf 4
    12" Fi BTL N3 dual 1.4 coils (0.7 wired)
    MB Quart Discus 2000.1 (true rms, same board as on AQ2200)
    65Ah battery (noname, but soon will change for Stinger 1700)
    0/1 Ga from (only + connected directly to battery)
    Alpine 9886 HU


    What we need:

    Maximum dB output that we can take from it. Im thinking about 1.7 cuft clean vol. and four 110mm diameter tube ports tuned 50-53 Hz. But they are too long, what do you thing maybe it will be enough to use three tubes? Also what do you thing about clean vol. that i choose for box? And maybe somebody know Golf 4 resonance?
    Thanks.


    P.S. Now sub is playing in music box, you can watch it on YouTube:

    With just 2kw on tap, you can go bigger on the box. I wouldn't do 1.7ft^3 unless you're running a good 5kw to that sub. Do 2.5ft^3 with the same 50hz tuning.

    Go with a bigger box, you aren't running that much power to it. Big box and big port. What's the resonance frequency of the vehicle?

    Better yet, just grab a 6" or 8" aeroport so you can adjust the length to find the best tuning for tour install.

    If you are only doing 2000w or 2500w, you could do a huge box (theoretically) for burps.
